Patent GB-2039659-A (GB)
Title: Coupling device for furniture panels
IPC: F16B12/14
Filed: 1979-01-17
Abstract: A coupling device for wooden furniture panels comprises a headed bolt (1) having a screw threaded stem (2), a socket member having a transverse recess or aperture (7), and an internally threaded retaining nut (8) housed generally within the aperture (7) with its longitudinal axis generally alignable with that of the transverse aperture. The nut is capable of slight radial movement within its housing but is prevented from freely rotating. The diameter of the aperture or recess is larger than that of the bolt stem thereby allowing free insertion of the bolt stem therein to threadedly engage with its retaining nut. The socket member may have a rectangular cross-section. <IMAGE>

Title: Feed Systems for Tobacco Conditioners
IPC: A24B3/02
Filed: 1979-04-09
Abstract: A bale feed system for continuous tobacco conditioners. A first conveyor (16) arranged at right angles to a row of conditions (32, 34, 36) moves the bales towards the row of conditioners, and just in front of the row and running parallel to it is a track for a traversing trolley (30) onto which the bales are transferred when they reach the end of the conveyor. The trolley is then transversed to present a bale to one of the conditioners on receipt of a demand signal. In order to provide a continuous and closely spaced supply of bales on the first conveyor a special delivery trolley may be provided, which moves along the first conveyor end automatically deposits a bale immediately behind the previously loaded bale. <IMAGE>
Patent GB-2049977-A (GB)
Title: Improvements in or relating to receptacles for clamps for optical fibres
IPC: G02B6/38
Filed: 1979-05-23
Abstract: A receptacle for a clamp (7) for an optical fibre has an outer member (1) and an inner member (2) forming a cylinder. A movable member (3) fits inside the cylinder. When the clamp (7) is inserted into the outer member (1) to allow latches (6) to engage recesses (5) in the outer member (1), the clamp (7) abuts against the movable member (3) causing the springs (10) of the movable member (3) to be compressed against the inner member (2). When the clamp (7) is released the pressure of the springs (10) on the clamp (7) cause the latches (6) to be forced against the rear edge (16) of the recesses (5) and hence the clamp (7) is held firmly in place. This system absorbs the override of the clamp (7) during the latching process. A projection (4) prevents excessive override of the clamp (7) which could cause fracture of the springs (10). Clamp (7) may hold the end of an optical fibre. A photo diode or a clamp for a second optical fibre may be housed in member (3). <IMAGE>

Bearing washers 8, 9 render the cradle 2 freely pivotal relative to the boat launching trolley about the vertical axis of the support column 2. To load the boat the boat is first inverted and supported with its transom on the cradle 1. The bows of the boat are then lifted manually and the boat freely rotated about the vertical axis of the column 2 until it lies over the car roof rack. <IMAGE>

Patent GB-2072696-A (GB)
Title: Oil Shale recovery process
IPC: C10G1/02
Filed: 1980-04-01
Abstract: In a process for the retorting of oil shale wherein hot flue gases (14') containing oxygen are used for preheating the raw oil shale (10) in a series of stages, the flue gas is reheated at 56 between preheating stages by burning a combustible sludge 46 therein. The preheated shale 10'' is retorted at 24 with a solid heat carrier to produce cleaned pyrolysis vapours 38 and a bottom oil 40 which is separated (e.g. by a centrifuge 42) into a clean bottoms oil 44 and the sludge 46. The requirement for additional fuel to heat the gases to operational temperatures is reduced and the sludge is eliminated as a waste by-product of the process requiring separate disposal. The entrained particulate matter is removed and disposed of along with particulate matter normally produced within the process. <IMAGE>

The fins 20 have flanges 22 which prevent the feed of powder from the hopper but, on rotation of the shaft, serve as a screw feeder to dispense powder at a rate dependent upon the speed of rotation of the shaft, or, in a second embodiment, the depth of entry of the fins into the outlet. <IMAGE>
Patent GB-2056672-A (GB)
Title: Optical fibre sensor
IPC: G08G1/04
Filed: 1980-08-01
Abstract: For sensing a moving body, including vehicles and personnel, a fibre- optic cable 1 is laid across the path of the moving body and light transmitted through the cable. Pressure of the body on the cable causes variations in the light transmission which can be detected. Different bodies or vehicles may be distinguished by their characteristic transmission loss patterns, axle weights may be measured, or speeds measured if the cable comprises a loop to produce two signals. In the latter case the light is not reflected back down the fibre by a mirror 9, as shown, but the detector is placed at the end of the fibre opposite the end by the source 7. The light may be chopped or modulated sinusoidally. <IMAGE>

Patent GB-2059077-A (GB)
Title: Plant watering indicator device
IPC: G01N33/24
Filed: 1980-09-22
Abstract: The device comprises an elongate member 11 which is insertable into soil and has a layer 14 of hygroscopic material, calcium hydroxide, disposed thereon. At the end of the member not inserted into the soil there is a transparent plastic coloured film 16, which covers the calcium hydroxide layer and seals the layer by means of tape pieces 18 and so on. There is a gap 19 in the layer disposed beneath the plastic film. In use the indicator is inserted into the soil and, if sufficient water is present, the water is attracted up between the film and the member and the calcium hydroxide changes from opaque to translucent whereby the colour of the member is contrasted against the colour of film above the gap, giving a visual indication of the water content. <IMAGE>

Title: Methods of making semiconductor bodies for integrated circuits
IPC: H01L21/761
Filed: 1980-12-09
Abstract: The side walls of a recess or cavity in a semiconductor substrate (10, 13) are masked with an insulating layer (7) before depositing material (113) in the cavity by vapour phase epitaxy. The deposition is terminated when the surface is level with that of the substrate. A small groove (V3) is left at the edge of the epitaxial region as opposed to an extension of the monocrystalline material onto the upper face of the mask which occurs if the sides of the recess are exposed. The masking layer may also cover part of the floor of the recess. In a double stage embodiment the epitaxial growth is continued to project above the original surface the recess thus defined is filled by the same method. Various semiconductor devices may be formed in the different surface regions to form an integrated circuit. <IMAGE>

Title: Manually-operable valve means
IPC: B05B9/01
Filed: 1982-03-12
Abstract: Manually-operable valve means control the dispensing through an outlet (4) of pressurised fluid from a container. The valve comprises a housing (1) having an inlet (2) for connection to a container, a valve member (3) in the housing (1) which incorporates the outlet (4) and engages a seating (7) surrounding the inlet (2). A manually-operable member (5) has lugs (28) to engage notches (26) on the valve member (3), and a spring (6) acts on the manually- operable member (5) to urge the valve member (3) into a closed position. Manual operation of the member (5), against the loading in the spring (6), allows fluid pressure to move the valve member (3) axially away from the seating (7) and into an open position. The valve means is provided with a locking mechanism (32) which, on angular movement of the member (5) acts to retain the member (5) in a position in which the valve is open. The locking mechanism (32) consists of cooperating parts on the member (5) and the housing (1), and may be lugs (33, 36) or a pin and slot mechanism (not shown). <IMAGE>
